Answer:

d 5,15,19

Step-by-step explanation:

The sum of the shortest two sides must be longer than the longest side. That is only the case for selection D.

If the sum is equal to the longest side, the segment ends will meet, but the "triangle" will look like a line segment. Many authors do not allow such a thing to be called a triangle. Hence, 'b' is not an answer to this question.

(Some authors <em>do</em> allow such a triangle, in which case, there would be two answers here: B and D.)

Consider the following proability density function: f(x) = { kx. 0<= x< 2, k(4-x). 2<= x <=4, 0. otherwise. find the

Gnesinka [82]

The value of K for which f(x) is a valid probability density function is 1/4.

<h3>How to solve for the value of K</h3>

$\int\limits^4_0 {fx(x)} \, dx =1$

$\int\limits^2_0 {Kx} \, dx +\int\limits^4_2 {K(4-x)} \, dx =1$

$K[\frac{2^2}{2} -0]+[K[4(4-2)-(\frac{4^2}{2} -\frac{2^2}{2} )]=1$

open the equation

$K\frac{4}{2}+K[8 - (\frac{16}{2} -\frac{4}{2} )] = 1\\$

$2K+K[\frac{4}{2} ]=1$

2K + 2K = 1

4K = 1

divide through by 4

K = 1/4
